JBL's site has 3143 and 3145 schematics, but no 3144.

Anyone know where that might be available?

It looks like 3144 was used with 2235H/2221H/2425J/2405 in the 4344

Hello,

The 3144 is the same as the 3145 and it was used in the 4344.
2235H/2122H/2425J-2307-2308/2405.

Thanks Giskard. I'd also picked up on your answer to this on another thread a while back.

Fixin to build two of these. The center-tapped inductors are in JBL's parts book and I ordered them, but haven't seen the goods yet.

Cool! :)

Did you order them from the Pro Parts website or did you talk to a person?

Giskard,

From the web site. The part numbers appear to be

61020-01R0 for 1.0mh

61018-0R16 for .16mh

... gleaned from the 3155 schematic which has a more complete parts list.

Yeah those parts are for the 3155.

The 3144 and 3145 parts are 41090 for the tapped 1.0 mH and 50344 for the tapped 0.16 mH.

I really can't remember which were set to what, but I'm thinking one set was set to -6 dB and the other set was set to either -3 dB or -4 dB.

Anyway, I'm sure it will all work out.

Thanks for those numbers. It looks like JBL messed up the order, so I have a chance to get the proper inductors if they have them.

FWIW, the 3155 schematic is labeled -4db
so the 3144 must be -6

"Thanks for those numbers."

You're welcome.

"FWIW, the 3155 schematic is labeled -4db so the 3144 must be -6"

That would be it then. I just couldn't remember off-hand and didn't think about it too hard :)

If you can't obtain them I have used the alternative of split air core inductors successfully
